LOG LOADER.

SPECIFICATION forming part of Letters Patent No. 309,103, dated December9, 188%.

Application filed May 2!), 1883.

1' 0 rtZZ whom it may concern:

Be it known that I, FREDERICK F. Sono FIELD, of Aseoda, county of Iosco,State of Michigan, haveinvcnted a new and useful Int provenient inLog-Loaders; and I declare the following to be a full, clear, and exactdescription of the invention,such as will enable others skilled in theart to which it pertains to make and use it, reference being had to theaccompanying drawingspvhich form a part of this specification.

My invention consists in the combinations of devices and applianceshereinafter speci-- lied, and more particularly pointed out in theclaims. I

In the drawings,Figure l is a plan View of an apparatus embodying myinvention. Fig. 2 is a side elevation. Fig. 3 is an end elevation of aportion of the same. Fig. 4 is a separate view of one of the parts.

The object of my invention is to provide an improved log-loader, adaptedto loadlogs onto a carriage commonly employed in saw-mills, which shallbe capable of ready and easy operation.

I accomplish my object as follows:

As illustrated in the drawings, A represents the ordinary carriage.

13 represents the frame in which the circular saw is engaged.

0 represents the floor.

1) represents the nigger.

E is the skidway of my improved loader.

F is an operating shaft or roller beneath the floor, said shaft orroller adapted to be driven by friction or other means.

f represents a crank or eccentric at the ends of the operating-shaft.

G represents conuecti ng-bars secured to said cranks or eccentrics attheir lower extremities.

H represents a cant lever or bar ofsuitable form, preferably constructedas shown in Fig.

4, having a toe-piece, h, and an angular arm, H, the extremity of saidarm being hinged or pivoted to the upper extremity of theconnecting-rod. The cant-lever is pivoted in the skid (X0 model.)

way, as shown in dotted lines in Fig. 2.

It is evident that when the toe of the lever projects and the angulararm is depressed to thelevel of the surface of the skidway the toepieceswill hold the log in place; but when the operating shaft or roller isrotated, so that the too is depressed and the angular arm elevated, thelog resting upon the cant-lever and held in place by the toe-pieces willbe projected downward upon the circular carriage. The length of thecant-lever is such that as one log is projected forward oif the skidwaythe an gular arm will be projected between it and the following log insuch a manner that but one log will be loaded upon the carriage at atime. The continued rotation of the operating-shaft will again depressthe angular arm and elevate the toe of the cant-lever, thus letting thelog forward upon the face of the cant-levers,where it will again be heldin place by the elevated toes.

two timbers on each side,so that the cant-lever can be pivoted betweenthem, though said levers may be pivoted to the skidway in any suitablemanner.

The friction of the rollerl, by which the op eratingshaft is rotated,may be controlled in any proper manneras, for instance, .by the leverIand said friction-roller may also operate the nigger in any ordinarymanner.

\Vhat I claim is- 1. In device for rolling logs from a skid to asaw-carriage,a series ofrocking arms mounted on a transverse shaftconnected to said skid, in combination with a pulley rotatable at will,and a .rod connecting the pulley to at least one of said rockingarms,substantially as set forth.

2. The combination, with the skidways E and log-carriage A, of thecant-levers H, pivoted to rock in a vertical plane, and each constructedat one end with the toe-piec-e h, and at the other end with a dependingangle-arm,- H, the rods G, pivoted at one end to the said angle-arms,and the shaft F, having crankarms f pivoted to the lower ends of therods, substantially as described.

3. The combination, with the skidways E and log-carriage A, of thecant-levers H, di-

I will be projected above the surface of the skid The skidway ispreferably constructed of reotlypivoted on the skidways, and eachhavpivots, and each provided with a toe-piece, h,
